US technology company’s engineers want to exploit solar power and the falling cost of rocket launches

Google is hatching plans to put artificial intelligence datacentres into space, with its first trial equipment sent into orbit in early 2027.

Its scientists and engineers believe tightly packed constellations of about 80 solar-powered satellites could be arranged in orbit about 400 miles above the Earth’s surface equipped with the powerful processors required to meet rising demand for AI.

Ruling in case brought by Getty Images against Stability AI is seen as a blow to copyright owners

A London-based artificial intelligence firm has won a landmark high court case examining the legality of AI models using vast troves of copyrighted data without permission.

Stability AI, whose directors include the Oscar-winning film-maker behind Avatar, James Cameron, successfully resisted a claim from Getty Images that it had infringed the international photo agency’s copyright.

Scientists say almost all have weaknesses in at least one area that can ‘undermine validity of resulting claims’

Experts have found weaknesses, some serious, in hundreds of tests used to check the safety and effectiveness of new artificial intelligence models being released into the world.

Computer scientists from the British government’s AI Security Institute, and experts at universities including Stanford, Berkeley and Oxford, examined more than 440 benchmarks that provide an important safety net.

From publishing falsehoods to pushing far-right ideology, Grokipedia gives chatroom comments equal status to research

The eminent British historian Sir Richard Evans produced three expert witness reports for the libel trial involving the Holocaust denier David Irving, studied for a doctorate under the supervision of Theodore Zeldin, succeeded David Cannadine as Regius professor of history at Cambridge (a post endowed by Henry VIII) and supervised theses on Bismarck’s social policy.

That was some of what you could learn from Grokipedia, the AI-powered encyclopedia launched last week by the world’s richest person, Elon Musk. The problem was, as Prof Evans discovered when he logged on to check his own entry, all these facts were false.

System rewards soldiers who achieve strikes with points that can be used to buy more weapons in an online store

A computer game-style drone attack system has gone “viral” among Ukrainian military units and is being extended to reconnaissance, artillery and logistics operations, the nation’s first deputy prime minister, Mykhailo Fedorov, has told the Guardian.

Drone teams competing for points under the “Army of Drones Bonus System” killed or wounded 18,000 Russian soldiers in September, with 400 drone units now taking part in the competition, up from 95 in August, Ukrainian officials said.
